隨著西門子變頻器的大力推廣后以及用戶對(duì)西門子變頻器的口碑傳播后，使得西門子變頻器在市場(chǎng)上受到群眾的大力追捧，不過(guò)用戶都會(huì)根據(jù)自己的實(shí)際工藝要求和運(yùn)用場(chǎng)合選擇不同類型的西門子變頻器，那么在選擇西門子變頻器時(shí)，選擇者應(yīng)該注意些什么問(wèn)題呢？選擇西門子變頻器應(yīng)該從哪些方面進(jìn)行選擇呢？本文將給大家一一講解。
對(duì)于這個(gè)問(wèn)題，我們需要從不用的角度進(jìn)行分析和選擇。1、從變頻器負(fù)載特性上面進(jìn)行選擇
一般從負(fù)載特性進(jìn)行選擇的，都是類似于吹風(fēng)機(jī)等一下電氣，那么對(duì)這類型的，建議選擇西門子變頻器的mmv/mdv、mm420/mm440。
2、實(shí)際電動(dòng)機(jī)電流值作為變頻器選擇的依據(jù)
應(yīng)充分考慮變頻器的輸出含有豐富的高次諧波，會(huì)使電動(dòng)機(jī)的功率因數(shù)和效率變差。因此，用變頻器給電動(dòng)機(jī)供電與用工頻電網(wǎng)供電相比較，電動(dòng)機(jī)的電流會(huì)增加10%而溫升會(huì)增加20%左右。所以在選擇電動(dòng)機(jī)和變頻器時(shí)應(yīng)考慮到這種情況，適當(dāng)留有余量，以防止溫升過(guò)高，影響電動(dòng)機(jī)的使用壽命。
3、考慮西門子變頻器的緊湊型
推薦SINAMICS G120C緊湊型變頻器，在許多方面為同類變頻器的設(shè)計(jì)樹立了典范。包括它緊湊的尺寸，便捷的快速調(diào)試，簡(jiǎn)單的面板操作，方便友好的維護(hù)以及豐富的集成功能都將成為新的標(biāo)準(zhǔn)。
我們?cè)趤?lái)看看對(duì)于選擇西門子變頻器我們應(yīng)該注意那些事項(xiàng)呢？
1、變頻器若要長(zhǎng)電纜運(yùn)行時(shí)，此時(shí)應(yīng)該采取措施抑制長(zhǎng)電纜對(duì)地耦合電容的影響，避免變頻器出力不夠。所以變頻器應(yīng)放大一、兩擋選擇或在變頻器的輸出端安裝輸出電抗器。
2、當(dāng)變頻器用于控制并聯(lián)的幾臺(tái)電動(dòng)機(jī)時(shí)，一定要考慮變頻器到電動(dòng)機(jī)的電纜的長(zhǎng)度總和在變頻器的容許范圍內(nèi)。如果超過(guò)規(guī)定值，要放大兩擋來(lái)選擇變
